maxing out power limit to +50% and overclocking hbm2 to 1100mhz (indicated as "OC" in below pics) result in worse gaming performance compared to stock balance mode on asus vega64 strix.

Maybe because the card throttles like crazy with the OC settings ?

You need to fill the hole... I would adhere on the other side.. thin copper sheet cut to size using thermal adhesive for all that "Holes" where the Chips Soar Sky High with no thermal sensor to FOOL YOU PEOPLE!!

Once you adhere the copper & add the Thermagon or that material you found in an old Printer? that could work possibly... You'll notice a Huge reduction in VRM temperature & the Whole PCB will cool down by 20-40C after you do this... That's 40 degrees celsius.
My 390X outperforms VEGA on Double Precision which is awesome! haha I love the 390X but the only thing I hate about it is... Lack of HDMI 4k 60Hz... 30Hz 4k is Ultra-Lame. So I need to get the Startech Displayport to HDMI adapter it's shorty stubby adapter allows 4k 60Hz on 390X.



It looks like your PCIe is stuck in PCIe 1.0 it appears on the VEGA & 290X stuck in PCIe 1.1 .... I would revisit the CHIPSET DRIVER & Checkout Anything PCIe GPU Related Settings in the Motherboard BIOS.

The 290X & VEGA if on a PCIe 2.0 motherboard should look at 6,500 MB/s READ/WRITE ... Half is 3,250 MB/s READ/WRITE this is all PCIe Bus here and that's PCIe 1.1 .... Half Of That is PCIe 1.0 Revision 1 ancient & slower than ever...

Good luck... Retest until you get those Read/ Writes Up & Scores will be a lot better as a result, especially at high resolution like 3840x2160 +.

It's not that. I'm aware of the 290x being x4, but its just a slave card for 2nd monitor, supposed to be gimped.

The vega is on a x16 gen 3

the gpu hot spot temp is near 100c under benchmarking and gaming test, maybe this hot spot temp throttles performance.

how high is the hot spot temp shown on gpuz 2.4 on yours vega56/64????

Typical r9 290x launch-like thermal loss though HBM should be able to achieve immense performance gains once power heat loss is very low & all chps cooled so the Black Chips are cooled around the GPU. You could simply adhere a long copper shim over them & add paste when it contacts.

I set my 390x to 1300mv @ 1172mhz core and memory @ 1250mhz @ 875mv here only 200 watts or so.

Hi,

just installed EK waterblock + backplate on my Vega 64 Air. I am slightly concerned about the GPU Temperature (Hot Spot) running FireStrike Graphics Test 1 in loop. Card is overclocked 1600-1650/1100 +50%PL and running high power Air BIOS. Backplate is also hot - barely can hold my finger on it opposite to gpu side.
What do you think?

Highest I seen mine was 55c. I took off original backplate and added an EK one with thermal pads.

So is there a general consensus on what the hotspot temp is?
Just tested and I'm reaching 72.4°C max on it during 4k RottR gameplay with my Vega 56 + Morpheus II

correction: GPU-Z was set to avg values. Hotspot max is 97°C

With hotspot temperatures that bad on the rear of the card, would it not be enough to buy some good thermal pads and an ek backplate? As long as there is air flow over the backplate.

To settle the question someone needs to do tests on waterblock without backplate, and with waterblock with ekwb backplate and thermal pads, and see if there is a significant difference in performance / stability / power consumption / oc headroom.

Don't think so, I would throw out a guess it's VRM or underside of the board/chip
